Construction and Expression of Hepatitis B Surface Antigen Escape Variants within the "a" Determinant by Site Directed Mutagenesis
Background: The antibody response to hepatitis B surface antigen (HBsAg) controls hepatitis B virus infection. The "a" determinant of HBsAg is the most important target for protective antibody response, diagnosis and immunoprophylaxis. Mutations in this area may induce immune escape mutants and affect the performance of HBsAg assays. Objectives: To construct clinically relevant recombinant muta...
متن کاملProduction of monoclonal antibodies anti-Taenia crassiceps cysticerci with cross-reactivity with Taenia solium antigens.
We describe the production of the potential monoclonal antibodies (MoAbs) using BALB/c mice immunized with vesicular fluid (VF)-Tcra (T. crassiceps) antigen. Immune sera presented anti-VF-Tcra (<20kD) IgG and IgM antibodies with cross-reactivity with T. solium (Tso) antigen (8-12, 14, and 18 kD). After cell fusion, we selected 33 anti-Tcra and anti-Tso reactive IgM-clones and 53 anti-Tcra speci...
متن کاملسطح خونی Anti-HBs در پرسنل بیمارستان کودکان امیرکلا، 1380
سابقه و هدف: حدود 5-3% جمعیت ایران حامل ویروس هپاتیت B می باشند که از این میان 15% دچار هپاتیت مزمن و مستعد ابتلا به سیروز و سرطان اولیه کبدی هستند. به دلیل نبودن درمان دارویی، موثرترین راه کنترلبیماری، واکسیناسیون با واکسن هپاتیت B است. بمنظور پاسخ به اینکه ایمنی حاصل از واکسیناسیون کامل تا چه زمانی دوام داشته و آیا نیازی به واکسن یادآور وجود دارد، مطالعه ای جهت ارزیابی وضعیت ایمنی کادر درمانی...
متن کاملPresence of maternal anti-HBs antibodies does not influence hepatitis B vaccine response in Brazilian neonates.
Recently, it was suggested that maternal hepatitis B surface antigen antibodies (anti-HBs) acquired transplacentally could play a negative role in newborn infants' immune response to the hepatitis B vaccine. We compared the hepatitis B virus (HBV) vaccine response in infants born to mothers previously vaccinated against HBV (n = 91) to infants born to mothers who were not previously vaccinated ...
متن کاملCoexistence of hepatitis B surface antigen (HBs Ag) and anti-HBs antibodies in chronic hepatitis B virus carriers: influence of "a" determinant variants.
In chronic hepatitis B (CHB), the persistence of hepatitis B surface antigen (HBs Ag) is sometimes associated with antibodies (Ab) to HBs (anti-HBs). To assess the hypothesis of the selection of HBs Ag immune escape variants in CHB patients, the variability of the HBV S gene was determined for patients persistently carrying both HBs Ag and anti-HBs antibodies and patients solely positive for HB...
